Link building is a crucial off-page optimization strategy. Multiple link-building strategies help in building backlinks directing to your website. Just gaining backlinks is not the only thing essential to rank top on search engines but you will need quality backlinks

Many people unintentionally make common mistakes when they build backlinks. Some common backlink-building mistakes to avoid are given below. 

Link to unreliable sites

Spam sites or duplicate content sites or porn sites carry a bad reputation and search engines never appreciate them. If you link to such sites, the search bots will certainly not love your site. Backlinks from unreliable sites like gambling or porn sites are not an accomplishment and need to be averted. If you gain multiple poor-quality links from unsecured websites, directories, irrelevant sites, and from pages with little content, then your ranking will suffer.

Focusing on dofollow links only

Building only one kind of backlink is bad SEO. A nofollow link is not valuable to search engine ranking because no juice is passed but offers an SEO boost when nofollow links are received from different domains [when you leave a comment on different sites]. Give equal importance to building nofollow and dofollow links. Use blog comments for nofollow link building and guest posting for building dofollow links. In this way, Google will not penalize your website. 

Buying/selling links

The search engine bots are getting smart and have algorithms that sense if the link is bought from other sources. If Google identifies that you are selling or buying links, then your site is penalized from search results. It is wise to invest in content or guest post writing services and publish on relevant blogs with backlinks pointing to your site.

Backlinks receiving from only high PR sites

It is good but blending high and low PR will yield better results. Lots of high PR links can look unauthentic. Google has not mentioned this but it is better to choose both. 

Ignoring toxic links

Toxic backlinks are irrelevant and unnatural that damages the search engine ranking of your website. Always perform backlink analysis and eliminate toxic links to be safe.

Making use of optimized anchor text

Google treats anchor text optimized links as black hat SEO, so be careful not to stuff keywords in the anchor text. Even avoid using the same anchor text on different blogs for link building. Your website may get penalized, so use various anchor text combinations while building dofollow links. 

Building links rapidly

If you are trying to achieve manipulative links quickly then you are in trouble with Google. Rather than aiming to get 25 links from low DA websites, it is better to get only 2 to 3 links from relevant and high DA links. Your aim has to attain a few quality links every day for effective SEO strategy

Backlink building is a challenge but an efficient way for achieving top ranking on major search engines. Whenever you work on a link building campaign for increasing search engine visibility, it is sensible to prepare a list of relevant sites to target. You can even depend on article directories only but switch to guest blogging because link building using guest posts works wonders!
